the display will show the following messa-
ge:
NOTE:the starting time is about 3 minutes.
NOTE:the appliance is endowed with a secu-
rity system that will stop the machine
after about 1.5 minutes of constant
functioning of the pump (to avoid pump
overheating). In this case, switch off the
main switch of the machine and then
turn it on again.
The machine is now ready to be used.
